DB Access at the beginning of the application

Hi all

I have an application (OS 5.0, 8520 Smartphone, developed on JDE plugin for Eclipse) which uses a SQLite database. The main of the application is something like that

SerializableAttribute public class MyApp extends UiApplication {}
Public Shared Sub main (String [] args) {}
MyApp PAP = new MyApp();
theApp.enterEventDispatcher ();
}
    
public MyApp() {}
If (! isForeground()) {}
do something
} else {}
do other
}
        
pushScreen (new MyAppMainScreen());
}

}

Debugging, I noticed that when I start the emulator I'm going through something (Yes, correct background), when I open the application for the first time I don't forward main method throgh, the second time I open the application I'm still going through other (in the foreground, right).

The first time and as the first, as I pass through the hand (so, backgorund), I have to do an operation on DB (as, for example, a request to decide on the application icon). The problem is that if I try to access DB when the application is in the background (do something Branch), I get a DatabasePathException. It seems that there is no such thing as the DB. If I try to access DB when the application is in the foreground (making another branch), I have no problem.

Someone knows how can I access the DB first I turn to the main method of my application?

Thanks in advance.

Kind regards

Gianni.

I wonder if maybe the SD is not mounted at the time wherever the application received the notice of power. You can check this by calling FileSystemRegistry.listRoots (). If it is not yet available, register a FileSystemListener with the FileSystemRegistry and wait for the root of the SD card to be mounted. If that's the problem, you can write your application to register two listeners and proceed with the work of starting only after having received both a notice of power and a ROOT_ADDED to the SD card.

    The application data folder is just a re - direct to the new version of the short name.  It is only there for compatibility, and since he is not a real file, you cannot open it.

  • How to lock access to the application user interface?

    Hello

    Our user interface application is configured to start automatically in the background when the BlackBerry is turned on.

    We have a configuration property (ShowUserInterface) in the application that will allow users to access the user interface by clicking on the application icon.

    Application continues to run in the background regardless of whether or not the ShowUserInterface configuration setting is 1 or 0.

    If the device is configured with ShowUserInterface = 1, the user interface does not appear to the user until the user clicks on the icon of the application. If the user closes or closes the application then it will continue to run in the background and maintain its condition.

    By clicking on the application icon again will open the application in its state of the screen.

    If the device is configured with ShowUserInterface = 0, then the user interface does not appear even when the driver click on the application icon.

    Please help how to achieve this?

    A code snippet

    public class MyApplication extends UiApplication
    {
        private Configuration config;
    
        private BackGroundThread _thread;
    
        public static boolean fromService = true;
    
        // Boot
        public static void main(String[] args) {
            if (args != null && args.length > 0 && args[0].equals("gui")) {
                // code to initialize the app by icon click
                fromService = false;
                MyApplication app = new MyApplication();
                app.enterEventDispatcher();
            } else {
                MyApplication app = new MyApplication();
                app.enterEventDispatcher();
            }
        }
    
        public MyApplication() {
            if (fromService) {
                _thread = new BackGroundThread(); // create a new separate thread
                _thread.start(); // start the thread
    
            } else {
                if (config.isShowUserInterface()) {
                    pushScreen(new LoginScreen());
                } else {
                    // what to do here?
                }
            }
        }
    }
    

    When the user clicks on the icon of the application and config.isShowUserInterface () = false in this case I'm not pushing any screen of the application. It is for me only IU lost Focus error.

    Any help will be appreciated.

    Thank you

    Look at acceptsForeground().  I think that you can simply return config.isShowUserInterface ().

  • Access to the applications of Builder Websheets

    Hello

    I want to give the developer role to one of our users, so it can develop a specific websheet of applications

    Problem is this setting a user as a developer still requires access to or another builder or sql application workshop

    I wouldn't give any of that, because they could access the application builder page and remove applications without any problem

    In the Web application sheet there is a button Builder, is possible to hide it somehow?

    I don't see any possibility to do, I tried with the chrome, definition of the element plugin: visibility: hidden and it works, only problem, is that I have no idea where to add this attribute to make it permanent

    Thank you!

    Hello

    To allow a developer to 'create' applications they need the privilege of Application Builder.

    I'm no expert with Websheets, but I'm sure that all 'development' is from the front-end of the application, so the user does not require access to the APEX server.

    If you have two options:

    (1) you will need configure a new application Websheet to this person whenever they need to reapply; OR

    (2) create a new area of work/drawing away applications, you don't want him to have access to and they have access to full development.

  • Use the ADF security to grant access to the application

    Hello

    One of our customers has to move their forms ADF application. The customer also wants to implement SSO using Kerberos. I could implement the ADF to the application security.

    The Application has two types of users whose information is stored in the USERS table in the database-

    1. Users of the application (not a domain user)
    2. Active Directory/domain users.

    What the clients want to do, is that if the user belongs to the domain, while the user must be able to view the home page directly. If the user is not a domain user, then the login page must be displayed and the user must be authenticated before the redirection to the home page.

    The first part, i.e. to implement SSO for users in domain works. But I don't know exactly how to proceed with the Application users.

    Can I create a custom authenticator that connects to the database and authenticate users of the Application?

    Any suggestion and pointers will be helpful.

    Thanks and greetings

    Tinto

    You probably don't need to create the custom authenticator.

  • 10.11.6 not have access to the applications or browsers, slow Finder & sparadic

    Had the unfortunate experience of strike updates pending popup and el capitan starts automatically updated at 11.6.

    With the update lost access to all applications with a pop - up indicating that the file is incomplete or does not properly.  Preferences system and spot light do not work.  Finder is sparadic and often extremely slow.

    I tried the reboot via safe mode does not work.  I tried the other update through safe mode does not work.

    Downloaded the update manually and I tried to update regular and safe mode with manual down load the file.  No change.

    Used the r command to download a copy of stand-alone 11.6 and entrust the fresh.  Did not work.

    Have not been able to try to use timemachine as finder has problems with external drives where the timemachines resides. Only, it no longer responds. Refreshs after several minutes, but has yet to show the contents of the folder.

    What can we do?  Use of end 2012 mini mac.  (any experience with el capitan has been extremely negative, first upgrade to 11.4, then upgrading to 11.5 and now 11.6 were overly long and extremely difficult if manually or auto-update. None have worked smoothly)

  • How to restrict access to the service web application deployed on weblogic for user group only

    I built the web service application in jdevelopler 11.1.1.7. Their security policy applied in the web service of the default Oracle policy which is (policy: Wssp1.2 - 2007-Https-UsernameToken - Plain.xml)

    Now all want to access the web service application must provide the name of user and password in the header section of the SOAP request to meet the requirement of the policy.

    the following steps I'm trying to restrict access to the application of web service with a specific group of users among users of weblogic:

    Connect to the weblogic administration console

    Create user or group of users

    Click on the links of deployments

    Click the sub-tab political

  • Professional Development System: Can not build the Application

    Hello

    I have the LabVIEW Professional Development System 2015 on my computer.   According to National Instruments, this version of LabVIEW has already provided with the Application Builder.  However, when I try to compile a standalone application, I don't have access to the application of the manufacturer. I've referenced the tutorial here and think that I do everything correctly: http://www.ni.com/tutorial/3303/en/#toc1

    If please see the attached screen shot and notice how I do not have the option ' new > application ", as claimed by the my system of professional development tutorial * must * have. How can I access the Application Builder with my professional development system?  Should I enable it?  If so, how should I do this?

    Thank you

    Go to OR under the National Instruments License Manager in the Start Menu.

    Make sure it is turned on it.  It should have happened automatically.  But if you had some odd order of installation, or maybe don't have access to the internet when it installed first, that she might leave the hanging of activation.

  • Unable to provision the Application - 11.1.2.2 user

    I'm trying to configure a user for one of our applications, but seem unable to do. They are part of a security access to four applications and, for each group, an Ad Hoc user role, Planner and view user assigned. I entered the Services shared and deleted all three rolls for the application of the security group, had the user, disconnect, then reconnect. They still have full access to the application! We tried to transfer and create security filters, which did not work. Not sure what we can try at this point, it's weird.

    We understood the question. The security group was part of a larger group configured to access these same applications. If we removed the two, the user has correctly off put in service for the application. Silly question that is much too long to figure out.
